To all whom, it muy concern:

as fully set forth hereinafter and as illustrated' in the accompanying drawings, in whieh- Figure 1 is a side elevation of an apparatus embodying my improvement; Fig. 2, an end elevation; Fig. 3, an enlarged view in part seetion; Fig; 4, a View showing a modification. There are two supporting heads or frames A A for the banks or skeins of yarn or other material to be dyed, moreel-ized, or otherwise treated, and there are two or more tanks F G,

l above which the. said supporting-heads are suspended in such manner that either head may be carried above either of the tanks and then lowered therein for any desired length of time and then again elevated, preferably being. so eounterbalancedthatthese operations may be performed with the exercise of but little labor upon the part of the attendant. As shown, both heads are supported by a revolving shaft E, having at the upper end a cross-arm H, carrying two pairs of pulleys 11 14 15 15, over which pass cables 13, arranged in pairs, as shown', one end of each cable being 'connected to the upper bar B of the supporting-frame A and the other e d of the cables being attached to the upper ar 13' of the snpporting-frame A', whereby the two frames counterbalance each other, the inner ends of the bars B B' being recessed to receive the shaft E, which serves as a guide in the vertical movementsof the supporting-frame.

At the lower ends of the supporting-frames are cross-'bars D D', in which turn freely smooth-faced pins 1, projecting from the opposite sides of said bars, said pins 1 correspending to similar pins 2, projectingfrom the go upper bars B Il', upon which pins are placed meshing with each other and combined with suitable means for rotating them-as, for in- Gpo stance, with a pinion 4 upona worm-wheel 19,

turned by means of a worm 6 on a shaft?, provided with a hand-wheel S.

It is necessary to set the cross-bars B 13' at proper distances from the cross-bars D Df, according to the length of the hnks or skeins,

and also to stretch the same to prevent shrink` ing during mercerizing or dyeing, and I therefore make the cross-bars B B' adjustable with respect to the cross-bars D D'. 'This may be done by suitable appliances; but, as shown, connecting-rods .fl {#,attached to the lower bars, are threaded at their upper ends, extend through the upper bars, and receivenuts 10 10, which are the hubs of gears 20, turning on the upper cross-bars B B-I and meshing with a pinion 21, connected with a hand-wheel 1S. upon a shaft 16, which turns in the frame and on which turnsa ratchet-disk 17. A pawllS, with a beveled lower end, engages the notches m in the disk 17 and from the latterextends a handle 16. Vy vibrating the handlel and disk 17 the pinion 21 can be turned intermittently to turn the gears 20 20 and apply any necessary power to tighten the banks upon the pins 1 2. By turning the hand-wheel the' nuts are rotated, thereby carrying the crossbar B up or down upon the rods 9 9. y

After the material carried by one of the supporting-heads has been introduced into one of the tanks' and operated upon by the liquid therein the carrying-head may be elevated and then turned to a. position above another tank and be again immersed, andl where there are more than two tanks'this may.
